R.I.P. William Alston (1921-2009)

I only learned a couple of hours ago about the death of William Alston. I never met him, I have only read one of his articles, and philosophically he played a leading role in putting Christian epistemology back on the map. But he was the dissertation adviser of Garey Spradley, one of my college philosophy professors. I took 8 courses with Professor Spradley and he taught me at least half of what I know about how to rigorously, carefully, and humbly pursue philosophical questions.
